This invention relates to concrete construc. tion and particularly to means for forming a ribbed floor structure. 1

An object of the invention is to provide means for forming concrete cross-ribs without the use of the usual temporary soifits, or cross bridging. I

Another object is to provide such means which are adjustable, whereby varying sizes of ribs may be constructed by use of the same forming means. y

Another object is to provide such forming elements which have means for bonding plastic material to the under surfaces thereof, such as in the formation of a ceiling.

These obj ects are attained by the means described herein and set forth in the accompanying drawings, in which: 7

sofiits. These soffits are positioned between and the open ends of'the tiles, at these places, are closed by means of end closures fastened upon the tiles. Passages are thus provided,

extending between the tiles transversely and longitudinally thereof, so that when concrete is poured over and around the positioned tiles, 7

the plastic material enters into said passages and forms ribs crosslng at right angles. The

temporary soffits upon whichthe edges of the tiles are supported extend in one direction,

that is, at right angles to the beams, and these soihts, together with the side walls of the tiles serve to form or mold the concrete ribs running parallel with the tiles. The cross ribs are formed in the spaces occurring at intervals in the tile rows, and are molded by the end closureplates on adjacent tiles and by short cross sofiits extending between the longer soffits at right angles and in substantially the same'plane therewith. Heretofore,

it has been, common to provide wood soflits This entailed a considerable amount of construction work,

eliminated.

Moreover, by the-use of means herein described both a large andaminute degree of .adjustment of the soffits, is made possible.

Another advantage arises in connection with the metal lath usually employed in this type of construction for forming ceilings. Sheets of this metallath, are laid upon the open wood centering initially, and the ties are positioned-upon the metal lath.

With reference to the drawings:

The tiles 15 have sides lfiand tops 17. The

metal lath 18, as shown herein, isof the type displayed in the patent to M. S. Goldsmith,

No. 1,168,627, and in applicants co-pendingapplication, Serial Numberv 127,149, filed August 4, 1926, in which the lateral edges 22 of units of-lath 18 are turned up for frictionally binding-the sides of the tiles. End closures 19 close one end of the tiles 15, being secured thereto by means of ears 20 attached to closures 19 and bent backwardly against which, by means of the present invention, is j idesired,

samev plane as the bottom edges. of tiles. 15-.v

The ends 25 of plates 23 protrude outwardly beyond the sides 16 of tiles 15. A dove tail rib 26 extends longitudinally of the central portion of each plate 23; Rib 26-rises above the upper surface of plate 23 and is preferably formed by bending 'themat'erial ofplate 23 so that the opening 30 of rib 26 liesin the plane of plate 23, and is more restricted than the area enclosed by the body portion of rib- 26, whereby a key formation results.

Asshown in Fig. 1, the: plates 23,. in the positioned tiles, areadapted to be placed in "opposed relation, their outer longitudinal edges overlapping, asindicated more clearly in Fig. 6, whereby a; soffit is provided'uponwhich concrete may be'poured for forming a cross rib or beam. As willbe: seen in Fig. 1,

i'the ends--25 of plates 23, have afirm: bearing on the soflits 27 secured to beams 28.

By further reference to Fig- 6, it will be therewithand has side portions-280 with a dove tail rib 29'therebetween. As illustrated in Fig, 7, when it is desired to form a cross rib or beam of greater than the average-- size, the tiles are positioned.- so that a space intervenes between the outer longitudinal edges of the plate's23. Thereaftenthe-bridge plate 270 is positioned by placing the side portions- 280 upon the similar portions of plates 23', so that the opening 30 provided bythe rib 29, comes directly above the space separating the opposed plates 23. A greater amount of adjustment may be had: in this type of sofiit, due to the fact that the overlap of both portions 280 maybe increased or decreased as ,In the modification shown in Fig, 8, a single soffit member 31 is substituted for the overlapping endplates heretofore described, said. member 31being attached to or integral with the end closures 191 of two adjacent tiles. Spaced dove tail ribs 26 may be provided in the sofiit member-31.

The modification in Fig.g9 provides for an independent sofiit member 32 having itslateral edges upturned and doubled upon themselves to provide channel'sockets 33. The bases 24 of end closures 19 are upturned to form flanges 3 f adapted to be received in the channel sockets 33 of member 32- It is evident that member 32 maybe of any desirable width and be provided with one or more of the dove tail ribs 26.

As illustrated in Fig. 10, the sofiit member 35 may be provided with a plurality of perforations 36, and the dove tail rib shown in the other modifications, omitted.

It should be noted that in all. these modifications, a comparatively light metal may be used in constructing the sofit members, the

dove tail rib serving the double purpose of stiffening the soflit members for bearing the load of concrete, and likewise, asexplained, of affording bonding means for ceiling. In constructions where no ceiling plaster is to be applied to the under surfaces, of the soflits and consequently where no key shape or dovetail is required, any suitable cross sofiit, such as that illustrated in Fig. 12 and having a suitable strengthening rib such as 290. 12), may be provided. Cross soffits of this type may be formed either integral with or independent of the'en'd closures-:1

previously disclosed herein. v

Various othermodifications along the lines herein described, will suggest themselves. For example, if the ceiling beneath a givenfloor is not to be plastered or is to beof the suspended type, any form of stiffening means other than the dovetail rib, may be used in the soffit members. Moreover, other suitable:

modes of attaching the independent soflit members shown inFigs. 7 and 9' tothe eh sure bases 24 may be-developed; Such other.

modifications, however, come obviously with- 1n the spirit and scope of this invention. What lskclalmed 1s:
